The precision of a mechanical movement depends on the
individual habits of the wearer and can therefore vary. A
qualified Omega watchmaker can adjust the precision of
a watch to within the Omega tolerances, which are from
-1 to +6 seconds per day.
Other Omega mechanical watches
The majority of watches that do not have a chronometer
certificate have average precision tolerances of between
-1 and +11 seconds per day.

Quartz watches
All Omega quartz movements are produced in accordance
with Omega’s highly renowned procedures and quality
standards. Ambient temperature may affect the precision
of quartz movements, which can lead to variations of
between -0.5 and +0.7 seconds per day.
Quartz watches with thermocompensation
(calibre 1680)
This movement is fitted with an electronic module that com-
pensates for the effects of temperature on the movement’s
precision. These watches are accurate to within +/- 0.055
seconds per day.
The precision of a mechanical watch cannot be compared
to that of a quartz watch, given that the two are based on
different technologies.
